tOneTobject of the present invention is to provide a sash lock designed-to hold the upper and lowersash of a windowin sc cured position when the sashes are either in openor closed position. j 'A further object is to provide a sash lock ofthe' character stated-in which the ;parft-s automatigally function to interlock an upper and lowersash in closed position.

,A furtherobject is to provide a sash lock of the character stated which after automatic locking of its parts maybe manually adjusted to prevent sash rattling. -A furtherobject of the present invention is-to provide upon the upper sash of a winscope of the invention will be understood from the following fdow a pivotal and perforated member which when not in use may be folded over in horizontal position upon the sash lower rail.

With these and other objects in view, the invention consists of the novel construction hereinafter described and finally claimed.

The] nature, characteristic features and more fully description 7 taken in connection'with the accompanying drawings forming part hereof, and in which: Fig. 1, is a fragmentary view of an upper and lower window sash equipped-witha sash lock embodying theinvention and illustrating the lower sash slightly raised. a l ig.2, is a view in section takenupon the line 22 of Fig; 1.

, Fig. 3, is afragmentary view in section illustrating the upper -and lower sash in i a closed position and the sash lock adjusted to prevent rattling of the sash.

r For the purpose of illustrating my invention I have shown -lIl'tl16 accompanying drawings two forms thereof which are .at

present preferred by me, since the same have and reliable results,

been found in practice to give satisfactory although'it is to be un derstood that the "various instrumentalities of which my invention, consists can be variously arranged and organized and that my invention 'is not limited] tofflthe "precise arrangement and organization of the" instrumentalities as herein shown and described. In the drawings, and refer-ringmore particularly to Figs. 1 to 4, the reference hum eral 1 designates the upper sash of a win-.

dow andlthe reference numeral 2 the'l'ower sash. Fixed-tothe lower rail '3 'of'the upper sash 1, as by screws 4, is a bifurcated'support 5 having at its top a-V-shaped recess 6. Having pivot-a1 relationas at? between the prongs ofthesuppor-t 5 fis a 'foldable' arm' '8 having-spaced apertures 9. 'When in use this arm is verticall disposed as I shown in Figs. 1, 2, 3 and 4," ut whennot in use may be folded. or shifted to-horizontal position so as to lie uponthe top of-the lowerrail 3 of the upper sash. I

'A' description will now be given of the partsas carried lby-thelower shaft which coacts with theparts of the upper shaft. *Fixed to the' topsrail '10 [of the lower sash 2,-as'

by. screws l-1, is a support 12 of "Ll-shaped cross-section. '-Movableflendwisethrough the and'the inner'endof whichis screw-threaded and is provided with a spherical jknob 1 5.

. The rod '13 is slidable through apertures the uprights of the uksha ped support 12 but itsinwardly slidable movement is limited "by ts outwardly slidable movement islimited by the sleeve 17 together. with pin 16; I Arranged between pin' 16 an d :the inner :wall. of the-outer uprightofwthe U-shaped member and surrounding ;the .rod "13"and its sleeve 17 is av coiledispring 718 for normally forcing: said rod2113. toward the'upper sash 1. a

with respect to one another as shown in Figs. 1 and 2, and the screw threaded end of rod 13 screwed into an aperture 9 of the arm 8 which, it will be understood, has been swung to vertical position around its pivot point 7. Inthis way windowsashes may be interlocked at desired heights. In closingthe lower window sash the parts are automatically interlocked for the reasonthat the'knob 15 of pin 13 first engages within V-shaped notch 6 and as the lower sash is further low ered the said notch acts as a cam surfaceto force rod 13 outwardly so that when the sash 2 is fully lowered the knob 15 ofrod 13 may automatically snap into aperture 19'of'support uponthei upper sashs While this cen nectionis sufficient to;retain the sash in interlocked position,r almore secure and rate tlingproof connectionmaybesecured by the manual operation of screwing the-inner end of' rod 13 firmly into aperture, -19 ,to cause the rails3 and of the-sash to form a tight joint ,]w- I J 1 -.It may not be desired to employthe arm 8 in which case I use in connection with the parts shown upon the top of the upper rail of sash 2 the support shown in Figs. 5 6, it

. being understoodthat this support is secured to the top of the lower railof'sash 1. This support, whichiis designated 20, is similarin; all respects to support 5 with the exception 7 that it is of solid cross-section instead of bein'g bifurcated. Inconnectionwith spring I pressed rod -13and its adjuncts thefunction j of interlocking the sash in closed position maybe obtained automatically and rattling of the sash prevented. Y What I claim is: 1. A combinedautomatic sash; fastener andjanti-rattler comprising a U-shaped bracket fixedto the lower sash of a window,

, a spring pressed rod, the forward end of I which isj s'crewthreaded, movable through smoothbores, in the uprights offlsaid U- u shaped member, a'pin fixed to said, rod to which is screw threaded, movable through smooth bores in the uprights of said U- shaped member, a pin fixed to said rod to I disposed \l-shaped notch and horizontally disposed screw threaded opening therebelow,

said opening being in alignment with said rod with-the tapervof the wall of said notch} leading directlytoward said Opening,w11erei i by in the closing of thelower sash'the end of said rod engagessaid notch to force said rod'a'g'aln'st the action of its spr ng in order that said rod may. lengagesaidopenmgito interlock the sash automatically, :saidrod when screwed into saidopening serving .to provide an anti-rattler,- and an arm pivoted to; the bracket havingjthe notQh, there1 n,- said arm having s'pacedscrew threaded apertures therein and being arrangedto be swung into verticalposition so that: saidhrod maybe screwedinto an aperture of saidarmto fasten the upperand lowersashes at, predeterv mined heights.
